  "(Update 3/16/17, 7:52am PT: AMD has confirmed that the cores are disabled in a symmetrical alignment). AMD is disabling cores on all of the models, but most still employ the entire 16MB cache, which makes some of the six-core models particularly attractive (based on price) compared to the eight-core Ryzen 7's. The Ryzen 5 1400 is the only model that features a trimmed L3 cache (8MB). The four-core 1500X with 16MB of cache is also impressive- the competitive i5's only come with 6MB of L3 cache, while the i7-7700K has a comparatively paltry 8MB. It will be interesting to measure the performance impact of the healthy L3 cache allotment.

  Most importantly, the four-core models will employ a dual CCX design. This means the processors will likely suffer the same lower performance in gaming scenarios, and in some cases it might be worse, as the processor will be forced to allocate threads to the second CCX more frequently.

  A single four-core CCX, or only one active CCX on a dual-CCX chip, would help avoid many of the problems that appear to restrict Ryzen 7's gaming performance in many popular titles, and frankly, many enthusiasts were hoping this would be the the case. The four-core 1500X and 1400 have the same 65W TDP as the eight-core Ryzen 7 and the six-core Ryzen 5 1600X and 1600. We would expect a lower TDP or significantly higher clocks within the same TDP envelope with a single-CCX architecture. Retaining the dual-CCX design with active cores on both CCX is far from ideal, and the gaming performance disparity will likely continue"
